Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the object of this invention is to provide a kind of hydraulic lock fixed pattern blade clearance automatic mechanism, can be fast, accurately, reliably cutting edge is adjusted and locking positioning.
For achieving the above object, the present invention takes following technical scheme:
A kind of hydraulic lock fixed pattern blade clearance automatic mechanism, comprise cutting edge 6, cutting edge 6 is arranged on bearing 5, bearing 5 puts together on support body 1 by hydraulic nut 12 and bolt 7, two hydraulic cylinder 11 symmetries are arranged on support body 1 and pass behaviour both sides, hydraulic cylinder 11 piston rods stretch out the two ends that withstand on bearing 5, two wedges 4 are arranged on the side, two ends of bearing 5, with the hydraulic cylinder 11 relative both sides that are positioned at bearing 5 respectively, the relative laminating in inclined-plane of the inclined-plane of taper key 3 and wedge 4, taper key 3 slides in the groove of chute 2, chute 2 is arranged on support body 1, the screw head of the afterbody of taper key 3 and lift 10 is hinged, two lift 10 symmetries are arranged on the both sides, below of support body 1, two lifts 10 are by short connecting axle 13, long connecting axle 14 and the first shaft coupling 8 interconnect, stepper motor 9 is arranged on the transmission side of support body 1, by the second shaft coupling 16 and power shaft 15, lift 10 is carried out to transmission.
The cloth elongation α of described stepper motor 9, the speed reducing ratio i of lift 10, its screw rod helical pitch p, the inclined-plane slope r of taper key 3 and wedge 4, according to stepper motor 9 return pulse signal quantity n, obtains blade clearance adjustment amount s and is:
s=αnpr/360i
In on-the-spot application, when blade clearance adjustment according to the supplied materials strip thickness detecting, only need launch corresponding pulses number to stepper motor 9, hydraulic cylinder 11 and hydraulic nut 12 coordinate corresponding degree of tightness action can complete automatic adjustment.
The present invention is owing to taking above technical scheme, and it has the following advantages:
(1) regulate the speed fast, precision is high, adjusts means automation.
(2) adopt hydraulic nut and hydraulic cylinder to cooperatively interact and lock, locate convenient reliable.
(3) kind of drive is that stepper motor is direct-connected, simple in structure, is convenient to safeguard.
(4) this mechanism form is simple, takes up room little, is also convenient to the upgrading of existing equipment.

Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in detail.
As Fig. 1, Fig. 2, shown in Fig. 3 and Fig. 4, a kind of hydraulic lock fixed pattern blade clearance automatic mechanism, comprise cutting edge 6, cutting edge 6 is arranged on bearing 5, bearing 5 puts together on support body 1 by hydraulic nut 12 and bolt 7, joint hole on bearing 5 is slotted hole so that it moves while adjusting, two hydraulic cylinder 11 symmetries are arranged on the biography behaviour both sides of support body 1, hydraulic cylinder 11 piston rod heads are spheric, it stretches out and will withstand in the plane at bearing 5 two ends, two wedges 4 are combined and installed on the side, two ends of bearing 5, with the hydraulic cylinder 11 relative both sides that are positioned at bearing 5 respectively, the relative laminating in inclined-plane of the inclined-plane of taper key 3 and wedge 4, the inclined-plane slope of wedge 4 and taper key 3 is identical, taper key 3 slides in the groove of chute 2, chute 2 puts together on support body 1, the screw head of the afterbody of taper key 3 and lift 10 links together by pin, two lift 10 symmetries are arranged on the both sides, below of support body 1, two lifts 10 are by two short connecting axles 13, long connecting axle 14 and two the first shaft couplings 8 interconnect, stepper motor 9 is arranged on the transmission side of support body 1, by the second shaft coupling 16 and power shaft 15, lift 10 is carried out to transmission, control its lifting action.
The cloth elongation α of described stepper motor 9 is 1.8 °, the speed reducing ratio i of lift 10 is 24, the helical pitch p of its screw rod is 6mm, the inclined-plane slope of wedge 4 and taper key 3 is 1:12, in the time that needs are adjusted blade clearance, stepper motor 9 is sent to corresponding pulses number of signals n, sideshake will be adjusted automatically, in the time needing the blade clearance adjustment amount s of 0.01mm, pass through
s=αnpr/360i
Can be calculated pulse signal n is 96, and to rotate 1.8 ° of corresponding blade clearance adjustment amount s of a cloth elongation be 0.0001mm to stepper motor 9, and precision is quite high, meets demand of industrial production completely.
Operation principle of the present invention is as follows:
When supplied materials strip thickness reduces to adjust blade clearance, the oil pressure unloading of hydraulic cylinder 11 and hydraulic nut 12, bearing 5 becomes loosening on support body 1, then stepper motor 9 is rotated in the forward certain angle according to number of pulses n, drive lift 10 to rotate by the second shaft coupling 16 and power shaft 15, its screw rod rising promotes taper key 3 and slides along chute 2, thereby extruding wedge 4 is together with the corresponding sideshake adjustment amount of bearing 5 translation s, then the piston rod of hydraulic cylinder 11 stretches out bearing 5 diebacks between itself and taper key 3, last hydraulic nut 12 fills to carry bearing 5 is locked on support body 1, blade clearance reduces adjustment process to be completed.In like manner, in the time that supplied materials strip thickness increases, stepper motor 9 counter-rotates, thereby taper key 3 declines, then hydraulic cylinder 11 stretches out, and promotes bearing 5 translations, wedge on it 4 and taper key 3 are pasted extremely, and last hydraulic nut 11 fills and carries locked bearing 5, completes sideshake and increases adjustment process.The present invention regulates the speed soon, precision is high, can meet industrial requirements completely, has good popularizing application prospect.
